• With the USB output you can charge your mobile phone or other USB enabled devices. The output power is 5
Volts - 1 Ampere. The weather station cannot be operated via the USB output.
9. Weather forecast symbols (Fig. 4)
• The weather station has five different weather symbols (sunny, slightly cloudy, cloudy, rainy and stormy).
• The weather forecast relates to a range of 12 hours and indicates only a general weather trend. The accuracy
is about 70 %.
• For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean the product
is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is
expected to get worse but not necessarily rainy. The accuracy is about 70 to 75%.
• The sun symbol also appears at night if there is a starry night.
Note:
Please note that the forecast symbol will become more defined in the course of operation. The forecast sym-
bol is active right from the start, however, the reliability of the forecasts increases with the amount of data
collected. The sensor must adapt initially to the reference level at the site.

10.4 Dew point

• The interdependency of temperature and relative humidity is expressed by means of the dew-point:
If the air is cooled continuously at constant absolute humidity, then the relative humidity will steadily
increase up to a maximum of 100%. If the air is cooled further, then the excess water vapour is separated out
in the form of water droplets.
• Press the HEAT/DEW button, to show the current dew point.
• DEWPOINT and the temperature appear on the display.
• The indoor and outdoor humidity values disappear.
• The display automatically switches back to the current display of temperature and humidity.
11. Additional outdoor transmitters
• For having more than one additional outdoor transmitter select with the 1/2/3 switch in the battery compart-
ment of the outdoor transmitter for each single outdoor transmitter a different channel. The reception of
the new transmitter will be transmitted automatically to the basic station. Press and hold the CH button on
the basic station or restart the basic station according to the manual.
• The outdoor values will be shown on the display of the basic station. If you have installed more than one
outdoor transmitter, press the CH button on the basic station to change between the channels 1 to 3.

• Once registered outdoor transmitters (channels), which are no longer needed, can be deleted manually by
pressing the CH button for three seconds. Once a new outdoor transmitter is received, there will be another
indicator.
12. Positioning and fixing of basic station and the outdoor transmitter
• With the foldable leg at the back of the basic station, the basic station can be placed onto any flat surface or
wall mounted at the respective location by the hanging holes at the back of the unit. Avoid the vicinity of
any interfering field like computer monitors or TV sets and solid metal objects.
• With the hanging hole at the back of the outdoor transmitter, the transmitter can be wall mounted at the
respective location. Choose a shady and dry position for the outdoor transmitter. (Direct sunshine falsifies
the measurement and continuous humidity strains the electronic components needlessly).
• Check the transmission of the signal from the outdoor transmitter to the basic station (transmission range of
up to 60 m free field). Within ferro-concrete rooms (basements, superstructures), the received signal is natu-
rally weakened.
• If necessary choose another position for the outdoor transmitter and/or receiver.
